Because of the deserialize implementation that's automatically generated, at this moment the expected value for the public_key_store in the manufacturing server is a CBOR array of the DER certificate. This commit adds a new type PlainBytes which (de)serializes transparently, and makes the manufacturing server use it for the public key store. NOTE: this means that with this patch, the store format on disk changes. This store is a ReadOnly (the server will never write to it), but if anyone would've put a CBOR file in place, that will now fail to open. Raw DER was always the intention (and documented) format, but it still is a risk. Signed-off-by: Patrick Uiterwijk <patrick@puiterwijk.org> Fixes: fdo-rs#477
